CVE-2026-107639

Status: DeferredHigh (8.7)—

ILIAS before 9.24, 10.x before 10.12 and 11.x before 11.5 contains an argument injection vulnerability in assImagemapQuestionGUI that allows question authors to inject ImageMagick convert options via uploaded image filenames. Attackers can embed tab-separated options, which escapeshellcmd() does not neutralise, to write a PHP file under the web root and achieve remote code execution.

CVSS

Exploitation probability (EPSS)

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).

🎯 ATT&CK techniques

How this vulnerability is exploited and what the attacker gains, in MITRE ATT&CK terms.

Vulnerabilidad de inyección de argumentos en ImageMagick explotable por autores de preguntas con acceso autenticado (PR:L) para escribir archivos PHP bajo raíz web y ejecutar código remoto; impacto de ejecución de comandos vía web shell.

Inferred by our analysis agent from the official description, CVSS vector and CWE, and checked by a supervisor. May contain errors.
